To` all whom it may concern.'

Be it known' that I, NORMANWV. Sronnn, a citizen of the TJnited States, and aresident offtittsburgh. inthe county of Allegheny and State ofPennsylva-nia, have invented a new and yuseful Improvement in Couplers, of which the following isa specification.

My1 invention relates to railway-vehicle trucks, more especially. tohinge constructions vtherefor which will permit 'freedom of articulation between. the respective truck members constituting the body support.

It is amongthe object-s of this invention to provide a yielding and flexible connection between articulated trucks of locomotives to prevent excessive stressing and nosing of the members and .to assist in guiding on curves.

lt is a further object of my invention to provide a structurewhich shall be simple 35 but is adapted to' restrain relative lateral movement therebetween. v

In the accompanying drawing constituting a part hereof and in which like reference characters designate like parts,

Figure 1 is a plan view of a pair of trucks hinged in accordance with thisinvention; and

' Fig. 2 is a Side elevational view thereof, partially in cross section.

The structure comprises a pair 0f trucks 1 and 2having the usual side frames 3 which are journaled to a plurality of axles 4 in the usual 'manner'. The trucks are provided with cross center-bearing plates 5 provided with openings 6 adapted to receive center pins of the locomotive bodyto provide pivotal movement ofv the trucks. The adj acent ends 7 and 8 of the trucks 1 and 2, respectively, are provided with convex projecting bumpers and projectingsupport-` ing bracketsv 10. `pluralityof linksllfand 12, each provided with an elongated opening 18; andan annularopeninglll, are lpivot'ally. i' mounted at"th`e1r resili'ectfifve ends 'onthe' bumpers 9 by through bolts '15. f Altra-ns1 verse link 16 isLp-ivotally connected,at its re.- spective ends,` lto theA by suitable bolts 17.

vThe operation ofthe hinge lbriefly'as follows. Vh'enemployed on pusher locomo-I e5 tif-fes, the bumpers 9 are inj Contact and ythe 1 and Qpivot about thejconvexfsur 'faces thereof to permit guiding action `ofthe fore truck when.roundingacurve, that Vis further facilitated by the transverse link 164 longitudinal movementbetween the bumpers 9, and the hinged transverse link is adapted to restrain lateral movement between the truck members but permits of longitudinal and pivotal movement between the respective bumpers.

The relative movements trucks are essential in the chording of the cab with respect to the trucks `when the latter are rounding a curve in order to maintain the center distance kbetween thecenter bearings 5 of the ytruck members. Thisy construction reduces, to a largel extent, the thrust and resultant projecting brackets 10 Aflange wear on. the wheel.

The elongated `opening in the link 11 permits of relative betweenl the I Although I have described a specific emi'-` bodiment of my invention, it will beobvious to those skilled in the art that various modications may` be made in the details of con' struction without departing from the princi ples herein .set-5 forth.

For instance, thetransverse link 16 maybe provided with* ksprings to permit of yielding lateral ref.

straint and to increase or decrease the movement betweenv the brackets 10;

I claim as my invention comprising a pair of cooperating.' bumpers, a longituclinally disposed link connectlng Lupports associated with said bumpers.v

21A `locomotive articulated truck hinge comprisinga pair of -co-operating bumpers,

a v'longitudinally disposed link pivotallyj connected to said bumpers and `atransverse vsaid bumpers and a transverse link pivosf i' ktally connected, `at its respective ends,- -to link pivotally connected, at its respective ends, to supports associated with said bumpers.

3. A locomotive articulated truck hinge comprising a pair of co-operating bumpers, a longitudinally disposed link pivotally connected to said bumpers and a transverse link pivotally connected, at its respective ends, to supports associated with said bumpers, said longitudinal links having an elongated opening to permit of relative longitudinal movement of said bumpers.

4l. A locomotive articulated truck hinge comprising a pair of co-operating bumpers, a plurality or longitudinally disposed links connecting said bumpers and a transverse -link pivotally connected, at its respective ends, to supports associated. with said bumpers.

5. AY locomotive articulated truck hinge comprising a pair ot co-operating bumpers, a. plurality of longitudinally disposed links pivotally connected to said bumpers and a transverse link pivotally connected, at its respective ends, to supports associated with said bumpers, said longitudinal links having elongated openings to permit of relative longitudinal movement of said bumpers, and said transverse link being adapted to restrain lateral movement therebetween.

6. A locomotive articulated truck hinge Icomprising a pair of convex bumpers incooperative alinement With each other, a plurality of connecting links pivotally mounted on said bumpers to permit relative longitudinal movement thereof and a transverse link pivotally connected, at its respective ends, to projecting supports associated With said bumpers.

7. A locomotive articulated truck hinge comprising a' pair of convex bumpers in cooperative alinement with eachother, means for providing relative longitudinal movement and pivotal `movement therebetween,-

and means tor restraining relative lateral movement thereof.

in testimony whereof,y l have vhereunto subscribed my name this 7th yday of October, 1922.
